Abstract: A device configured for radiating a focused electromagnetic beam is proposed. Such device comprises: —a first (101) and a second (102) part having respectively a second n2 and third n3 refractive index and a first W1 and second W2; —a first contact area (100e1) intended to be between a host medium having a first refractive index n1 and in which the micro or nanoparticles are intended to be trapped or moved by a focused electromagnetic beam radiated by the device; —a second contact area (100e2) between the first part and the second part; and —a third contact area (100e3) intended to be between the second part and the host medium. The focused electromagnetic beam results from a combination of at least two beams among a first (NJ1), a second (NJ2) and a third (NJ3) jet beams radiated respectively by the first, second and third contact areas when an incoming electromagnetic wave (IEM) illuminates the device. The device is configured for having a direction of propagation of the focused electromagnetic beam tilted in respect of a direction of propagation of the incoming electromagnetic wave.

Abstract: A device (200) is proposed comprising a first part (101) of a first material having a first refractive index n1 and a second part (102) of a second material having a second refractive index n2 higher than n1. Such device further comprises at least one contact area (110) in between the first and second parts, radiating an outgoing electromagnetic wave (100o) when the device is illuminated by an incoming electromagnetic wave (100i). A projection of the at least one contact area along a direction of propagation of the incoming electromagnetic wave has a non-vanishing height lower than 1.2 times a critical height equal to a wavelength in vacuum of the incoming electromagnetic wave divided by the difference between the second refractive index n2 and the first refractive index n1.

Abstract: In example embodiments, an optical component includes a dielectric structure having a substantially rectangular cross-section with an upper surface and a lower surface. A first electrically conducting layer is provided on the upper surface, where the first electrically conducting layer has a first opening positioned to accept incoming electromagnetic radiation. The second electrically conducting layer has a second opening positioned to emit electromagnetic radiation, e.g. toward a CMOS sensor pixel in a silicon substrate. The dimensions of the optical component are configured to provide constructive interference for incident radiation of a selected wavelength.

Abstract: There are several types of plenoptic devices having a proprietary file format. At present, there is no standard supporting the acquisition and transmission of multi-dimensional information for an exhaustive over-view of the different parameters upon which a light-field depends. As such, acquired light-field data for different cameras have a diversity of formats. The notion of pixel beam, which represents a volume occupied by a set of rays of light in an object space of an optical system of a camera is introduced. The method according to the invention enables to provide data representative of a bokeh associated to a pixel beam. Such data representative of bokeh associated to a pixel beam enables the displaying of an image with good bokeh properties.
